He started the project by getting rid of the stock battery and moving to a pair of Lithium Polymer cells. They give the vehicle more power and more than twice the running time between charges. A couple of springs were added to the suspension system for a smoother ride. Turning had been a problem since the original design offered no control over how far the wheels turn. You can just make out the body of the servo motor he rolled into the system to allow for more precise turning.

The most recent addition is the HackHD camera on the front of the vehicle. It records to an SD card rather than streaming the video in real-time. Check out the clip after the break to see the interesting perspective achieved by filming so low to the ground. The one thing we would add is a cage around that board which retails at around $165.

They’re still vastly more suitable to the task than a $150+ development board. This is like turning your old android phone into a clapper circuit. For that kind of investment you could get five keychain cameras, orient them front-back-left-right-up, and combine them in software to get a very nice resolution 360 degree panoramic view.

Already tried the camera on my FPV Bixler. In fact I am working on a micro-quad which is capable of carrying this camera.
Also, while ground-based vehicles are a bit outdated, they are a fair bit of fun and the hacking counts too!
